# PyHRM
[PyHRM]() is a python based library for processing <span><b>High Resolution Melting (HRM)</b> data, especially, DNA melting signals to extact features like <i>'Melting Temperatures', 'Take-off and Touch-down points of melting signal (Temperature at which peak start rising and temperature at which peak falls down)','Peak prominences',and 'Area Under the curve'</i>. Additionally, the library offers interactive visualization for DNA melting singal and vision based filtering, to eliminate noisy signals from the data and provides only genuine peaks with all the above mentioned features.<span>


## Installing with PIP

```
python -m pip install PyHRM
```

### Example
```
from PyHRM import melt

hrmdata = obj.data_read(path = './path/file.xls', figure = True)
```
Alternatively,
```
import pandas as pd

```
## PyHRM.melt.MeltcurveInterpreter.plot
```
PyHRM.melt.MeltcurveInterpreter.plot(data,save = False)
```

The function takes a pandas dataframe contains signal values and render back the respective figure. The plot function takes any data like CT, MELT and as well as raw fluorescence, and gives back the corresponding visulazation.

<b>Parameters:</b>&emsp;<b>data : </b><i><b>pandas dataframe object</b></i>
<br>
<br>
&emsp;&emsp;&emsp;&emsp;&emsp;&emsp;&emsp;&emsp;A pandas dataframe contains signal values.

#reading the HRM data
hrmdata = obj.data_read(path = './path/file.xls')

#visualizing the data
fig = obj.plot(data = hrmdata, save = True)
fig.show()
```
## PyHRM.melt.MeltcurveInterpreter.melt_conversion
```
PyHRM.melt.MeltcurveInterpreter.melt_conversion(figure = False, return_value =False, download = False)
```
This methods only works for raw fluorescence data, and the input of this method is the class member itself. It converts the raw fluorescence signals into melting signals with signal smoothening.

<br>

### Example
```

hrmdata = obj.data_read(path = './path/file.xls')

#Extracting features of the melt signals
features = obj.feature_detection(return_values = True)
```
<br>

## PyHRM.melt.MeltcurveInterpreter.report
```
PyHRM.melt.MeltcurveInterpreter.report()
```
The method generates a report with the feature extracting data and it's corresponding melting signal figures.

<b>Parameters:</b>&emsp;<b>None</b>
<br>

```
from PyHRM import melt
obj = melt.MeltcurveInterpreter()

#reading the HRM data
hrmdata = obj.data_read(path = './path/file.xls')
